Refer to the following taxi fare arrangement.
Original fare (whole day)
First 2 kilometers $30
Every subsequent 200 meters $2
Suppose a late-night surcharge of $20 will be added to the original fare on any taxi trips from 1:00 am to 5:59 am. How will this surcharge affect the average travel distance of taxi passengers during late-night? Explain. (4 marks)
When a fixed lump-sum charge is added on a good, the relative price of the long-distance trips will decrease but the relative price of the short-distance trips will increase. The quantity demanded of long-distance trips will relatively increase while that of short-distance trips will relatively decrease, so the proportion of long-distance trips will increase. The average distance traveled increases. (4)
